fix(editor): door/window move — fix 2D+3D FPS collapse + finish modifier migration

The 3D MoveDoor/MoveWindow tools wrote useScene every frame during a move
(freeFollowAt + applyPreview alternating): the wall:move (R3F) / grid:move
(DOM) de-dup compared event.timeStamp across two event systems with different
clocks, so it never matched and the floor free-follow ran during on-wall
slides too, ping-ponging the host and churning the nodes ref → framerate
collapse in both 2D and 3D. Replace it with a single-clock wall-ownership
window (performance.now, ~4 frames): the floor follow stands down while a
wall/roof hit is fresh. On-wall slides now write no scene per frame (mesh +
useLiveTransforms only). Lower the live wall-cutout throttle 120→60ms now that
the per-frame churn is gone.

Also completes the door/window modifier-model migration (#10): Shift=cycle /
Alt=force-place, fully mode-driven snap, snapProfile:'item'; exclude
ground-line candidates from along-wall opening alignment; emit the move SFX
once per snapped step.
